How to split a string with the uppercase character in iPhone -

I want to separate the string with the occurrence of uppercase letters. Suppose I have a string like "IAmABoy". I want the resulting strings like

  I Am A Boy.  

How to do this? Is there a sample code? Please show me how to do this.

What is something simple about simplicity like some characters? Assume that some inputs like output string and NSStrings are supposed to be:

  NSUInteger length = [input string length]; (Nsuentegar i = 0; i  0 & amp; c> = 65 & amp; amp;; & amp;; & lt; = 90) {[outputString Attachment Format: @ "\ n% c" , C]; } And {[output string adenform: @ "% c", c]; }}
